Professor Dan Healy, one of my Engineering instructors back in prehistoric times,  had a favorite way of showing us how to do this kind of problem ... I mean the kind that's incredibly easy, but your own fear gets in the way and convinces you that you can't handle it.  Here is Prof. Healy's method.

For a few moments, call the square root of 5 by the name "cow".

cow - x = 4 .    Solve this equation for 'x' :

Add 'x' to each side of the equation:  cow = 4 + x

Subtract 4 from each side:                cow - 4 = x

Now, we can put the real value back in place of 'cow' :  <u>√5 - 4 = x</u>

That right there is a perfect solution.  But If you absolutely need to
know the number, then grab your calculator:

√5 = 2.2361 (rounded)

x = √5 - 4 = 2.2361 - 4 = <u>-1.7639</u> (rounded)

Please help! Problem is attached

Answer:

  (a)  -3

Step-by-step explanation:

The value of f(x) approaches 3cos(π) = -3 as x approaches π from either direction. The limit is -3.

__

<em>Additional comment</em>

The fact that the function is defined to have a different value at x=π simply means there is a jump discontinuity there. The function is <em>not continuous</em>, because the limit and the function value differ. That doesn't detract from the fact that there is a limit, and it is -3.
